Substance P TFA (Neurokinin P TFA) is a neuropeptide that functions as both a neurotransmitter and neuromodulator in the central nervous system, specifically targeting the neurokinin 1 receptor (NK1-receptor, NK1R).
[Sar9,Met(O2)11]-Substance P TFA is a selective tachykinin NK1 receptor agonist.[Sar9,Met(O2)11]-Substance P and septide (10-100 pmol per rat, i.c.v.) are equipotent in increasing mean arterial blood pressure (MAP) and heart rate (HR), yet they have dissi
Broad spectrum neuropeptide inverse agonist and antagonist. Potent full inverse agonist for the ghrelin receptor (EC50 = 5.2 nM); diminishes constitutive ghrelin receptor signaling. Also antagonist at tachykinin, bradykinin, CCK and bombesin receptors. In
[Sar9]-Substance P is one of NK-1 receptor agonist. The action of SP on progesterone metabolism was mimicked by the rNK1-specific agonist [Sar-9,Met(O2)11]-SP.
Substance P (1-9) is a nonapeptide that reduces the inactivation of substance P in the guinea-pig ileum and urinary bladder, and is responsible for various excitatory effects on central and peripheral neurons.
[Glp5,(Me)Phe8,Sar9] Substance P (5-11) (DiMe-C7) 是一种 Substance P 类似物,在大鼠大脑中对神经激肽 1 受体 (NK1R) 的作用与 Substance P 大致相等,但作用时间大大延长。[Glp5,(Me)Phe8,Sar9] Substance P (5-11) 能选择性地激活大鼠大脑间脑和中脑皮层的多巴胺代谢。[Glp5,(Me)Phe8,Sar9] Substance P (5-11) 还可增加大鼠运动活性,诱导成瘾剂寻求行为的恢复。
